[Public WebGL] Differing TypedArray#set behavior



While implementing TypedArrays, I came across a specific situation
that seems to be missed by the conformance tests. Here's a test:

  https://github.com/stephank/node-arrays/blob/master/test/typed-array-copy.js

This does a copy using `TypedArray#set` between two TypedArrays of
different types, but with the same backing store and overlapping
regions.

The test passes on Firefox, but fails on Chrome, Safari, Opera and Node.js.

Is the Firefox behavior the correct one here?
